Aachen, Germany, 1st April 2014: Magritek, a leading provider of compact NMR and MRI instruments, report on the use of their Spinsolve Benchtop NMR spectrometer at The BAM Federal Institute for Materials Research and Testing in Berlin.

The BAM Federal Institute for Materials Research and Testing operates under the guideline “Safety in Technology and Chemistry.” For the field of analytical chemistry, this defines tasks with the main emphasis on development and provision of certified reference materials (CRM), development and validation of complex analytical methods, methods for the assessment of analytical laboratories, and establishing and fostering national and international networks committed to the assurance of quality, reliability and comparability in analytical chemistry. The focus of Division 1.4 Process Analytical Technology (PAT) is the development and application of PAT technologies. This includes develop¬ment and validation of analytical online and at-line methods.

Dr Michael Maiwald and his colleague, Nicolai Zientek, MSc, use NMR in their daily research and development work. They use a high frequency 500 MHz online NMR spectrometer as their reference instrument. They “hyphenate” NMR with conventional online analytical techniques such as NIR, Raman, UV/VIS spectroscopy and, in particular, medium resolution NMR spectroscopy. As Dr Maiwald says, “Our aim is to develop techniques to bring the benchtop lab instruments “into the plant” and to show (in projects) how MR NMR could already be used for technical applications like online reaction monitoring. This led us to the acquisition of the Spinsolve Benchtop NMR spectrometer from Magritek.”

Asked why his group selected to use the Spinsolve, Dr Maiwald said “We were impressed with the spectra – the symmetrical line shape and narrow line width was achieved even in technical mixtures. This is due to the use of Halbach magnets. The stability we observed over a given period of time without preparing the instruments was extremely good. We have seen that the Spinsolve remains working in specification for as much as 48 h in a technical environment. Pre-magnetisation below the active region of the magnet is important to us for online measurements. As far as we see, the instrument meets this requirement.”

Describing the projects to date, Dr Maiwald, said he has used the Spinsolve for flow-through reaction monitoring experiments. These have included the simultaneous observation of 1H and 19F in an esterification reaction. This was observed within 1/16” FEP tubing using a 5 mm outer diameter

Dewar insert to keep the elevated reaction temperature. Looking ahead, Dr Maiwald and his group are planning to further improve online reaction monitoring with medium resolution NMR spectroscopy and develop automated data preparation and data analysis tools by developing chemometrics and automated signal processing tools.
